NCT07342582

Brief Summary

The goal of this study is to determine the burden of Rhinoviruses (RVs) as a cause of acute, severe, respiratory illnesses leading to hospitalization. A community cohort of 120 children between 12 and 36 months of age will be enrolled in the first year of the study and followed (when well and sick) for 36 months to identify the circulating RVs and provide samples to establish a host nasal transcriptome differentiating clinical from subclinical RV infections. A hospitalized cohort of 450 infants and children will be enrolled during years 1 through 3 of the study and followed for the duration of their hospitalization to investigate the findings of the community cohort. An additional 100 healthy children aged 5-17 years will be enrolled for age-match comparison with the older hospitalized cohort.

Outcome Measures

Primary Outcomes (2)

  • Aim 1: Summary of Rhinovirus Types Identified in Community Cohort

    To test study hypotheses, the study team will identify the circulating RV types in symptomatic and asymptomatic children.

    data collected up to 36 months

  • Aim 1: Unique Nasal Transcriptomic Signature of Clinical Rhinovirus Infections

    data collected up to 36 months

Secondary Outcomes (2)

  • Aim 2: Summary of Rhinovirus Types Identified in lower respiratory tract (LRT) infections and upper respiratory tract infections (URI), Reported as Percent in Common

    data collected up to 36 months

  • Aim 2: Proportion of Hospitalized Cohort with lower respiratory infections attributable to Rhinovirus

    data collected up to 36 months

Study Arms (3)

Younger Community Cohort (12-36 months of age)

Quarterly Surveillance Nasal Swabs and Nasal Swabs targeted around respiratory symptoms for up to 36 months of age, participants will provide one anterior and one mid-turbinate nasal swab sample

Diagnostic Test: Nasal Swab Healthy SurveillanceDiagnostic Test: Nasal Swab Sick SamplesOther: Sick Follow-up Survey

Hospitalized Cohort of Infants and Children

Generally healthy infants and children hospitalized for respiratory illness will provide one anterior and one mid-turbinate nasal swab sample

Diagnostic Test: Nasal Swab Hospitalized Cohort

Older Community Cohort (5 to 17 years of age)

Age-matched controls for older children in the Hospitalized Group, will be called upon as needed based on enrollment of hospitalized patients

Other: Older Cohort Control Group

Interventions

Families will be asked to collect nasal swabs from their children during specified surveillance months (February, April, September, and December). Caregivers will be instructed to only collect surveillance samples during these months if and when children have been free of respiratory symptoms for at least two weeks prior to sampling. Caregiver surveys are part of quarterly surveillance.

Younger Community Cohort (12-36 months of age)

Caregivers will be instructed to watch for respiratory symptoms and collect nasal swabs 24-48 hours after symptom onset. Caregiver surveys are part of sick sample collection

Younger Community Cohort (12-36 months of age)

2 nasal swabs collected upon consent, one anterior and one mid-turbinate

Hospitalized Cohort of Infants and Children

Caregivers are surveyed 7-13 days after sick sample collection

Younger Community Cohort (12-36 months of age)

Participants will be enrolled as needed based on enrollment of hospitalized patients

Older Community Cohort (5 to 17 years of age)

Study Population

Aim 1: Generally healthy male and female children 12 to 36 months of age living in Dane County and surrounding areas representative of the general demographics of the county. Aim 2a: Hospitalized male and female children between newborn and 17 years of age with acute onset lower respiratory tract infections. These children will span all demographic and socioeconomic groups. Aim 2b: Generally healthy male and female children 5 to 17 years of age living in Dane County and surrounding areas representative of the general demographics of the county.

Data Sharing

IPD Sharing
Will share

All of the raw RNA-sequencing data will be available in FASTQ files and all of the processed gene counts data and relevant metadata will be available in CSV files. It is customary and expected that the results of this investigation will be published in a scientific journal. All of the data underlying publications will be shared. All raw FASTQ data and aligned counts data will be deposited into the public repository Gene Expression Omnibus (GEO) at the end of the study, so that other researchers can freely make use of the data. The shared data sets will be available in GEO and we will adhere to their guidelines for what the datasets will include.
